    Mountains under the sea

    The multibeam on the RV Tangaroa scans the seafloor to produce a map of the seamounts.

    By the end of this activity, students should be able to:

    • understand the concept of underwater mapping of the seafloor
    • construct a model to simulate a seafloor and take readings
    • plot the results and use these to create a map.

    In 2017 the Seabed 2030 Project was launched at the United Nations (UN) Ocean Conference. It is aligned with the UN's Sustainable Development Goal #14 – to conserve and sustainably use the oceans, seas and marine resources. It is a collaborative project between the Nippon Foundation of Japan and the General Bathymetric Chart of the Oceans (GEBCO). It aims to bring together all available bathymetric data to produce a definitive map of the world ocean floor by 2030.
